Using drones for remote sensing of crop yield for programming

V. Lisenko, A. Opryshko, D  Komarchuk, A. Pasychnik

 

In the context of global markets the optimality criterion of crop farming is not maximum yield and product quality, but maximum profitability, which is determined by the ratio of the expected price of the finished product and its fabrication costs. Maximum economic efficiency is achieved by programming the yield. One of the means of programming is the rational use of mineral fertilizers based on the needs of plants. Traditional methods of determining the state of the crops include ground survey, the use of chemical reagents or different testers and are not suitable for mass use in making operating decisions for each field site.

Development and implementation of crop condition monitoring system using drones is an actual scientific and technical problem. Solution of this problem enables to obtain current information about the status of crops, to maximize the economic efficiency of commercial farm units.

The object of this study is the condition of crops, which estimating is based on the spectral characteristics of plants obtained by means of drones and ground survey.

The subject of the study is a relationship between the plant spectral characteristics and the level of availability of fertilizer elements for plants.

Approximating relationships for these scene modes were displayed based on the arithmetic values of the intensity of the color components for both sides of the leave. When the flash was used the approximation of data by relationship 2 the coefficient of determination was higher than 0.97.

Conclusions

  • The digital camera can be used in the field to indicate the level of nitrogen nutrition of corn without additional artificial illumination.
  • The most prospective camera’s scene mode is "daylight" for the "white balance" setting.
  • According to preliminary data, the most promising optical bands for the explorations in RGB are green and red.
  • In a pot experiment in phytotron it is advisable to analyze the whole leaf rather than a part of the upper leaves.
  • The future researches are needed to investigate the relationship between the plant optical parameters and plant nitrogen nutrition provision at different growth stages.
